To check the leveling on the balance, look at the leveling bubble on the floor of the weighing chamber. Analytical balance weighing accuracy is a measure of how close the displayed weight is to the actual weight of samples on the weighing pan. The analytical balance PCE-MA 200 is used to weigh a range of substances up to 200g / 7.05oz and measure their moisture content. It refers to unstable weight readings, which typically occur due to static charge and inconsistent temperatures. This is why analytical balances have draft shields. Faster weighing with improved repeatability and vibration filtering. The weighing capacities of Analytical Balances range up to 300g and they have display resolutions down to 0.001mg.

Many investigators simply zero out this effect and analytical balances that are meant for individual consumers, such as for body weight measurement, come in attractive shapes, colors and designs to make them blend with the décor. If extream accuracy is not important a top-loading balance will work just fine in measuring the accuracy of 0.001g. Analytical balances used in a pharmaceutical lab are used for extremely precise measurements, such as the microbalance capable of measuring 1 millionth of a gram, for instance. Two terms apply here. The definition of precision according to VIM 2010 (International Vocabulary of Terms in Legal Metrology) is: closeness of agreement between indications or measured quantity values obtained by replicate measurements on the same or similar objects under specified conditions. Five precautions to take for correct weighing of laboratory samples. Analytical balance programming, sample handling, sample placement on the weighing pan and day-to-day maintenance of the analytical balance are key.
